1 Claim.

My invention relates to cartons made of cardboard or breboard for use in shipping bottles of liquor and other such substances.

'I'he object of my invention is to provide an 5 improved construction embodying means for holding the locks on the inner end walls of the carton and protecting them by outer flap portions in such a manner that no part of the locking means can be reached without obvious muti- 19 lation or injury to the carton, and in which the carton must be mutilated in order to remove its contents.

A further object is to provide a construction in which the end walls are stiffened by the use of a 15 number of overlapping flap portions inclosed by an outer flap which presents a smooth unbroken surface to view.

Referring to the drawings which form a part of this specication:

Q Fig. 1 is a plan view of a carton embodying my invention.

Fig. 2 is a view taken on line 2--2 of Figure l.

Fig. 3 is a cross sectional view on line 3-3 of Figure 2.

25 Fig. 4 is a formed blank of sheet material such as cardboard, in which the dotted lines indicate scores and the solid lines indicate slits.

Fig. 5 is a perspective view showing the carton in its open condition ready to receive a bottle.

:2e In forming the carton, the blank is folded on the scored lines forming the inner rectangle, which provides a bottom portion I0, side walls I I and I2.

One of the inner end walls is formed by bends.; ing the portions I3 and I4 toward each other and interlocking them by use of the slits in the usual manner, and the opposite end wall by interlocking the portions I5 and I6 by a similar operation.

The top ends II-I'I respectively are then bent 10 on the lines I8-I8 respectively, outwardly and downward in contact with the interlocked portions, thus providing smooth rounded upper edges ISI-I9 of double thickness, and also covers the interlocking jointed parts.

L15 The next step is to bend the portions 2li-2D respectively on the lines 2I-2I respectively, upwardly and then bend them on the lines 22-22 respectively, and then on lines 23-23 respectively, then fold the ends 24 and 25 back upon 50 themselves as illustrated in Figure 5, to reinforce the end portions of the carton.

Thereafter the cover portions are formed by bending the material on the scored lines 21--21 respectively.

55 The cover portions 28 and 29 are formed withslits 30 for interlocking, and are also formed with notches 3| and 32 respectively, located as illustrated.

The end portions 25 are also provided with similar notches indicated by 33-33 respectively. 5 A lock consisting of a body portion 34 and a latch 35 both stamped from sheet metal, is permanently attached to each end of the carton, the body portions 34 being held thereto by prongs formed integral therewith in the usual manner, and located on the inner end wall portions I4 and I5 respectively, adjacent the upper edge thereof and near a corner of the carton, the lock at one end being located at the opposite side of the carton relative to that of the other lock, as illustrated in Figure 1.

The latch part of the lock 35 is permanently attached to its respective cover portion by prongs formed integral in the usual manner.

The portions 24 of the carton are slitted at 36 20 to form tabs 31.

When the carton is being closed, the cover portions 28 and 29 are folded in overlying interlocked relation as illustrated in Figure 1.

In the act of closing the carton, the shank of the latch is bent at a right angle and its free end is pressed against the tab 31 which bends inwardly and guides the shank thru the notch 33 into engagement with the body portion 34 and is permanently secured therein by snap engagement in the usual manner.

By reason of carrying the lock on the inner surface of the end wall, it is beyond the reach of any implement to unlock or detach it without visible injury to the carton and its destruction as a container.

It will be noted that the outer end wall is securely locked in engagement by reason of the end flap portion being bent back upon the adjacent section in such a manner that its end abuts 4o the inner wall of the carton, and that the two thicknesses of material thus provided act to materially strengthen and stifen the end portions of the carton.

Having thus described my invention I claim as new:

A carton of the character described formed from a single sheet of material, comprising a bottom and two side walls, each side wall carrying a cover portion arranged in overlying interlocked relation, and a latch carried by each cover portion located adjacent a margin thereof; said carton having duplicate end walls, each of which comprises end flap portions extending from opposite side walls, arranged in overlying interlocked relation to form an inner Wall, a tab portion carried by one of said flap portions and extending from the upper edge thereof over the outer surface of said inner wall, an outer end Wall portion extending from the bottom to the top of the carton and having a flap the end portion of Which is folded back under the flap and abuts the inner Wall to Secure the flap in locked position, and a lock carried on the inner side of the end wall under a latch: the construction being such that a latch may extend into the adjacent lock and be held in permanent engagement therewith.
